There is no prescribed method in the Code that explicitly tells us what to do. The advice is that it must be given consideration. There was a recently issued interpretation (BPV VIII-1-16-85) that stated this. That interpretation is paraphrased below.

Question: When superimposed static or dynamic reactions, as required by UG-22, are specified for the design of a pressure vessel, is it permitted to use an ASME standard product as defined in UG-11(c) produced in accordance with an ASME Standard referenced in UG-44 without performing supporting calculations that indicate the component is acceptable for all design conditions?
